The present invention relates to a film supply device that can automatically select and load a film into a carousel.

Conventionally, a plurality of supply magazines containing sheet films of different sizes were installed in a film supply device. It is common practice to selectively unload the supplies from the supply magazines and load them into the cassettes. However, the way in which X-grade film is used is that X-rays differ in size depending on the part of the human body being photographed. Not only is ilm used, but different types of modges wire film may also be used depending on the Oka size. If the type of X-ray film differs, the intensifying screen will also differ accordingly. Since intensifying screens are generally pasted inside cassettes, it is necessary to load different films into the cassettes even if the cassettes are of the same size. Conventional film feeding devices for X-ray cassettes detect the size of the cassette and feed and load film of a size that fits the size of the cassette, but the present invention allows X-ray film that fits the #cassette to be loaded into different types of cassettes. The present invention provides a film feeding device that automatically feeds the film.

An object of the present invention is to provide a film feeding device that can load X-ray films corresponding to intensifying screens pasted even in cassettes of the same size. At the same time, the supply magazine loading section for loading the loaded supply magazines can be opened at multiple locations, and the photosensitive material is taken out one by one from these supply magazines, and a cassette for loading the photosensitive material is installed through the film feeding section. In a film supply device equipped with a cassette mounting section, a detection mechanism is provided in the cassette mounting section to detect a discrimination means provided on the cassette exterior, and the detection signal activates a selection means provided inside the cassette cover to supply a specific supply. This is achieved by an X-ray cassette film supply device IK, which is characterized in that it loads a photosensitive material into a cassette taken out from a magazine.
